2 WATER EROSION
2.1  mm2 - cm2:
2.2  m2:
2.3 runoff plot 100, 200 and 1000 m2 interrill
small catchments (< 100 ha):
3 WIND EROSION
4 MASS MOVEMENTS
5 TILLAGE EROSION
Spatial scale considered:
6 TEMPORAL SCALE OF EXPERIMENTS
6.5 years: Based on the length of the rainy season.
6.6 remarks: Due to inter-annual variation of rainfall, many years observations are needed.
7 DESCRIPTION OF EROSION FACTORS STUDIED
7.1 Climate: Rainfall (amount, intensity and frequency).
7.2 Topography: Slope length and slope angle.
7.3 Soils: Old vs. newly cleared lands on sandy alfisols Sudanese zone, North Cameroon.
7.4 Vegetation:
7.5 Management: Conventional and reduced tillage.
7.6 Others: Soil cover is organic mulch or plastic mesh.
8 FIELD EXPERIMENTS Description of the field site and of the type of experiments and equipment involved for each of the erosion processes being studied:
8.1 Erosion process: Runoff, sediments, suspensions, crop yield, rainfall and soil moisture are recorded/measured.
8.2 Location (town, state, country): Mbissiri, Northern Province, Cameroon.
8.3 Equipment involved: Rain guage (daily rotation); humidimeter, oven, scales balances, motor pumps, electronic scale balanced.
8.4 Remarks: Different small materials needed.
9 LABORATORY EXPERIMENTS Description of the laboratory and the type of experiments and equipment involved for each of the erosion processes studied:
The experiment consist of runoff plots with size of 100 m2 (5x20), 200 m2 (5x40) and 1080 m2 (18x60). The main two sites are about 1000 m apart, each site having a rainfall station with one rain recorder. (Daily rotation).
